five suspects” were arrested as part of the operation, which was an alleged “multi-phase terror attack allegedly involved using explosive-laden drone aircraft to strike buildings in the vicinity of the event” designed to spark “mass panic and [drive] the fleeing crowd toward a sniper team poised to pick them off,”

Among those arrested was Tycen Proper, a 19-year-old Ohio man whose mother contacted local law enforcement last week with concerns about his firearms purchases and online communications, according to an FBI affidavit filed in the case.

An assistant federal public defender assigned to represent Proper, who's charged with firearms offenses and crimes including attempted murder of an officer or employee of the United States, did not immediately return messages seeking comment. Proper made an initial court appearance Monday in Columbus and faces a detention hearing on Wednesday.

Proper admitted in an interview with law enforcement that he participated in the planning of an attack, according to the affidavit, which says some members of the group began communicating with each other last March through a TikTok group called "Vanguard of the Old."

"The members of the group stated that they wanted to protect the United States, which they believed was headed in the wrong direction," the affidavit says. "Members of the group believed that the United States needed to be torn down so that it could be rebuilt. Some expressed a desire that people who were involved with Jeffrey Epstein should not govern the country."
